Serving the Greater Rochester Area and the Twin Cities since 1988

Since our humble beginnings in Rochester, Minnesota in 1988, K&S has grown to be one of the largest volume heating and air conditioning companies in Minnesota. We are honored to represent quality companies like Lennox and Carrier, but today's owners are demanding more...especially when it comes to warranties.

Due to our huge volume, K&S has been able to sit down with Daikin American Industry designers at their location, just west of Houston, Texas, and have furnaces and air conditioners built to our tough standards. Daikin's Texas location is the largest heating and cooling factory in the world. We are so confident in the K&S Diamond Series design, we can back each furnace and air conditioner with one of the strongest warranties in America.

DIAMOND 20
The Diamond 20 is the front runner in the K&S Diamond Series air conditioner family. With an industry leading rating in excess of 20 S.E.E.R. It also utilizes a Variable speed Modulating compressor that can vary the heat removal (cooling) capacity between 35% and 100%. This will provide cooling at the correct speed for any given day. It’s very important to have a unit large enough to cool your home on the hottest day. On the medium and light load days, having a unit that can slow down to run longer can greatly increase the dehumidification. This air conditioner must be installed with the “Diamond 98” furnace and the “Comfort Net” thermostat control. Together they are the Ultimate Diamond package and can offer the best heating and cooling possible and maximum summer time dehumidification.


RUBY 16
The Ruby 16 is the runner up in the K&S Diamond Series air conditioner family. With a high efficiency rating of 16 S.E.E.R., it also utilizes a 2 stage compressor. This allows the air conditioner to operate at full speed 100% on the very hot humid days, and it can also slow down to 60% to maintain temperature and increase dehumidification
dramatically. This unit works very well when paired with the “Diamond 98” or the “Ruby 98” furnace and the “Comfort Net” thermostat control. When paired with one of these two configurations you will have control of your homes humidity independently in cooling mode.


EMERALD 16
The Emerald 16 is the next in line in the K&S Diamond Series air conditioner family. With a high efficiency rating of 16 S.E.E.R., it is a great choice for replacing your old single stage unit with one that gets the job done better and saves you money doing it.


SAPPHIRE 14
The sapphire 14 is the next in line in the K&S Diamond Series air conditioner family. With a mid-efficiency rating of 14 to 15 S.E.E.R., it makes a great option for someone who just needs to add a new or replace an existing air conditioner, but does not need or want to replace the furnace. This unit provides an improved energy savings over the base line unit.


TOPAZ 13
The Topaz 13 is the next in line in the K&S Diamond Series air conditioner family. With a base efficiency rating of 13 S.E.E.R., this unit is built with the same great American quality as all the K&S Diamond Series units. It offers reliable cooling at today’s standard efficiency. A great match for the “Sapphire 96” or the “Topaz 82”.
